I am working on an iOS application. In this application I am trying to convert NSString to hexadecimal. But in some cases NSString contains special $, ¥, etc. This is where I am facing problem. These characters don't convert to hexadecimal.

Is there any way to convert special characters to hexadecimal?

Answer 1

Convert the string to NSData

[NSString dataUsingEncoding:]

Then using the data object you can output any base you want: octal, hex, decimal, binary.
